So the user interface might look something like this:

pdf = PdfPages('filename.pdf')
fig=figure()
# ...
pdf.savefig(fig)
pdf.annotate(123,456,'my text here',fontsize=12,font='Helvetica')
pdf.close()

Should the coordinates be raw PDF points measured from the bottom left
corner, or passed through the figure transformation (or something else)?
What sort of font properties would you expect to be allowed?

I think that's what the pdf backend would end up doing internally, at
least if anything like coordinate transformations or any interesting
font properties need to be supported. It sounds like a fairly easy
change.

While we're discussing multi-page pdf files, would it be useful to have
pyplot-level support for them? It shouldn't be too hard to have pyplot
track your currently open pdf file and make, say, savefig with no
arguments direct the output to that. I personally don't have a use for
that, but do you think it would be a useful part of pyplot?

[matplotlib-devel] browse svn link on home page

2009-08-28 Thread jason-sage 
Is there any chance someone could add a brief reference and link to the 
online svn repository somewhere on the front page of matplotlib?  Maybe 
in the sidebar under "Need help?":

For details on what's new, see the detailed changelog 
 **or browse the 
source code**. Anything that could require changes to your existing 
codes is logged in the api changes 
 file.


where "source code" links to 
http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/

I've run out of fingers and toes for counting how many times I have to 
click around and hunt this down (and I always forget to bookmark it or 
I'm on a new computer!)

Thanks,

Jason

Done, though I made the link point to trunk/matplotlib since I think
that is what most people will be interested in.

But bookmarks are helpful too :-)
